Abstract

Filter cloth or tape for fruit juice pressing is of polyester yarn; in the transverse direction, rubber loops with a dia. greately exceeding that of the yarn are woven or knitted in at a preset spacing, preferably each alternating with a course of yarn, or with 2 courses.

Description

Aus Polyestergarnen hergestelltes Filtertuch oder -band Die Erfindung bezieht sich aiif ein aus Polyestergarnen hergestelltes Filtertuch oder -band, wie es in Obstpressen Verwendung findet. Filter cloth or tape made from polyester yarns. The invention aiif refers to a filter cloth or tape made from polyester yarns, such as it is used in fruit presses.

Derartige aus Polyestergarnen hergestellte Filtertücher oder -bänder haben sich in Obstpressen gut bewährt. Nach Beendigung des Preßvorganges wird mit diesen Filtertüchern oder -bändern der Trester herausgetragen. Dadurch, daß der Ureter sich in das Tuch eingepreßt hat, löst er sich nur schwer von dem Tuch und häufig bleiben Tresterreste im Tisch zurück.Such filter cloths or tapes made from polyester yarns have proven themselves well in fruit presses. When the pressing process is complete, press these filter cloths or tapes of the marc carried out. Because the Ureter has pressed into the cloth, it is difficult to detach from the cloth and pomace residues often remain in the table.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Filtertuch oder -band der eingangs erwähnten Art anzugeben, das aufgrund seiner besonderen Struktur die in ihm befindlichen Tresterreste auszustoßen gestattet.The present invention is based on the object of a filter cloth or band of the type mentioned to indicate that due to its special Structure allowed to expel the pomace residues located in it.

Dies wird bei einem aus Polyestergarnen hergestellten Filtertuch oder -band insbesondere für Obstpressen erfindungsgemäß dadurch erreicht, daß in dem Filtertuch in vorgegebenem Abstand Gumm#schnüre mit einem den Garndurchmesser wesentlich übersteigenden Durchmesser in Querreihen eingewebt oder eingewirkt sind.This is the case with a filter cloth made from polyester yarns or belt achieved in particular for fruit presses according to the invention in that in the Filter cloth at a specified distance Rubber cords with a thread diameter substantially exceeding diameter are woven or knitted in transverse rows.

Vorteilhaft ist die Gummi schnur statt jeder zweiten Garnreihe eingewebt oder eingewirkt.The rubber cord is advantageously woven in instead of every second row of yarn or acted.

Eine andere vorteilhafte Ausgestaltung besteht darin, daß die Gummischnur jeweils statt jeder dritten Garnreihe eingewebt oder eingewirkt ist.Another advantageous embodiment is that the rubber cord is woven or knitted in instead of every third row of yarn.

Bei einem derartigen Filtertuch verformen sich unter dem Druck der Filterpresse die Gummischnüre und bei Entlastung vom Filterpreßdruck versuchen die Gummi schnüren aufgrund ihrer elastischen Eigenschaften ihre ur prungliche Form wiederherzustilen, wobei sie die Tresterreste aus dem Filtertuch herausziehen und eine einwandfreie Ablösung des Filterkuchens von dem Filtertuch oder -band gewährleisten. Gleichzeitig werden die Öffnungen im Filtertuch nach jedem Preßvorgang wieder geöffnet, weil die bei vollem Druck abgeplattete Gummisckniir nach dem Preßvorgang wieder in ihre alte Form zurückkehrt,wobei sich die Öffnungen wieder öffnen. Bei geringem Druck besteht zwischen den Guinmischnüren des Filterbandes oder Filtertuchs und der Druckplatte ein Hohlraum, der den ausgepreßten Saft leicht ablaufen läßt.In such a filter cloth, the deform under the pressure Filter press the rubber cords and when you are relieved of the filter pressure, try the Due to their elastic properties, rubber cords its original shape by pulling the residue out of the filter cloth and ensure proper detachment of the filter cake from the filter cloth or tape. At the same time, the openings in the filter cloth are opened again after each pressing process, because the rubber backing flattened at full pressure again after the pressing process returns to its old form, with the openings reopening. With little There is pressure between the guinese cords of the filter belt or filter cloth and the pressure plate a cavity that allows the squeezed juice to run off easily.
